Claims (2)

1. Способ прокатки холоднокатаных труб большого и среднего диаметров из сплавов на основе титана, включающий производство передельных бесшовных или сварных заготовок, прокатку их с одним или двумя перекатами в зависимости от размеров труб и марки сплава, отличающийся тем, что передельную трубную заготовку для прокатки холоднокатаных труб большого диаметра производят формовкой на вальцах с последующей сваркой продольных кромок в защитной среде аргона.1. A method for rolling cold-rolled large and medium diameter pipes from titanium-based alloys, including the production of seamless or welded billets, rolling them with one or two rifts, depending on the size of the tubes and alloy grade, characterized in that the billets for cold-rolled rolling pipes of large diameter are produced by forming on rollers with subsequent welding of longitudinal edges in a protective argon medium. 2. Способ по п.1, отличающийся тем, что передельную сварную трубную заготовку прокатывают в холоднокатаную трубу максимального диаметра с вытяжкой 1,2-1,4, а при последующих перекатах вытяжку увеличивают на 0,05-0,20 до 1,9-2,3 на последнем перекате.2. The method according to claim 1, characterized in that the welded pipe billet is rolled into a cold-rolled pipe of maximum diameter with a hood of 1.2-1.4, and during subsequent rolls, the hood is increased by 0.05-0.20 to 1.9 -2.3 at the last roll.
